ADJUSTABLE BALL-BEARING AXLE.

SPECIFICATION forming part of Letters Patent No. 667,063, dated January29, 1901.

Application filed February 14. 1900. Serial No. 5,127. No model.)

To (LI/Z whom it may concern.-

3c it known that I, ADDISON J. OLEVENGER, a citizen of the UnitedStates, residing at Ontario, in the county of Wayne, in the State of NewYork, have invented an Improved Adjustable Ball-Bearing Axle, of whichthe following is a specification, reference being had to theaccompanying drawings.

My invention relates to an improvement in adjustable ball-bearing axlesdesigned for use on bicycles, tricycles, motocycles, 850., but capableof being employed for many other purposes.

My improvement is fully described and illustrated in the followingspecification and the accompanying drawings, the novel features thereofbeing specified in the claim annexed to the said specification.

In the accompanying drawings, Figure l is an elevation. Fig. 2 is acentral longitudinal section. Fig. 3 represents the difierential screw.Fig. 4 is the key.

My improved adjustable ball-bearing axle consists of the two relativelymovable members Aand B, each of which is provided with a cone 0, whichbears against a ring of balls N, as indicated in Fig. 2. One of themembers is provided with a cylindrical stern D, which fits inside theother member, beingarranged to slide lengthwise therein. A slot E in theouter member receives a pin or screw F, inserted in the stem, so thatthe members are prevented from turning relatively to each other. Themembers are connected together by the difierential screw H, which isrotated by the key I, inserted through a central opening in one of themembers. The screw H is provided with two threads of different pitches,one, J, being of, say, twenty-four threads to the inch, while the other,K, is of, say, thirtytwo threads to the inch, so that a very fineadjustment of the cones relatively to each other may be made by turningthe screw.

My improved axle may be used in connec tion with any suitable hub orrevolving part having cones or bearings for the balls.

The stem D of member A extends nearly the entire length of the tubularpart of the member B, which tubular part has a length approximatelyequal to the distance between the cones, the purpose of the constructionbeing to impart strength and stability to the joint. In priorconstructions both members have had equal diameters and clutchconnections at the ends, covered by an additional sleeve. The presentimprovement avoids the use of such sleeve and provides a stronger andmore stable joint and adds to the strength of the axle as a wholeindependently of the particular form of the joint and provides for moreeasily fitting the two members in manufacture.

I claim The combination, with the divided axle, consisting of tworelatively adjustable members one titted within the other and eachprovided with cones, of the internal differential screw, and the splineand slot connection between the members, as and for the purposes setforth.
